Final answer:
HI molecules exhibit London dispersion forces and dipole-dipole interactions, but not hydrogen bonding or ionic bonding, due to the polar nature of the molecule.
Step-by-step explanation:
The intermolecular forces present between two molecules of HI are primarily London dispersion forces and dipole-dipole interactions. Hydrogen iodide (HI) is a polar molecule, resulting in dipole-dipole interactions between the hydrogen end of one molecule and the iodide end of another. However, hydrogen bonding is not present because hydrogen is not bonded to an atom like oxygen, nitrogen, or fluorine, which are necessary for hydrogen bonding. Even in polar molecules, London dispersion forces are always present, though dipole-dipole interactions are stronger. Thus, HI exhibits both London dispersion forces and dipole-dipole interactions, but not hydrogen bonding or ionic bonding.
